Auto Start Mobo

Hello all,
I'm just wondering before I try it, usually the power switch needs 2 wires to turn it on. I wanted to know if the motherboard would auto start with a jumper from a hard drive or would it just fry it? Any ideas are much appreciated. Thanks.

What you are suggesting to do and Digerati please tell me if I'm wrong here. You most likely would cause the MOBO severe damage and render it useless. MOBO's are not designed to do what you are suggesting. If your issue is a switch then a trip to a electronics store or find a old system and take the switch out of it.
What you are asking is something I don't believe any tech would suggest under any circumstances as a fix even temporarily due to risk of destroying the MOBO.
Digerati I am really interested to know what you think about this .

Confusion. The two jumper pins the front panel power switch shorts applies +5VDC to the PSU signaling it to power on. Drives, on the other hand, use +12V for power. I see no reason to jumper anything from a drive to a motherboard, and rshaffer is right - serious damage to the motherboard, and perhaps other devices attached to it (RAM, CPU, cards) could occur. Use the proper cables, ensure they are connected properly.
